•
ISDN extensions can belong to an incoming call distribution group (® 2.2.2 Incoming Call Distribution
Group Features) or idle extension hunting group (® 2.2.1 Idle Extension Hunting). In this case, an MSN
can be assigned.
•
If the last digit of the MSN is "0", all terminal devices on the same ISDN port receive the call simultaneously,
if the specification of each terminal device is available. To use the MSN whose last digit is "0" as an
individual MSN, system programming is required for each ISDN port.
•
ISDN terminal devices that receive power over the telephone line are not supported.
